To all whom t may concern:

' Be it known that I, RoaEn'r A. GALLY, a citizen of the United States, residing' at Cincinnati in the county of Hamiltonv and 5 State of hio, have invented certain new mencement ends of the correlated accompanlment notes, the interrupted perforations ,fof the initial part of each accompaniment note passing less air to their apertures of the tracker bar',

Striker pnelnnatics 7 are. provided adapt-4 ed for actuation by the note perforations 2, 3, of the music sheet 1 as said sheet is traveling ,over a tracker bar 8, which bar has the usual tubular yconnections t0 the valves of the said striker pneumatics 7. The

tracker bar 8 hasseveral oi its'end aperw tures connected by tubes 9 to the usual primary pneuinatics of the control valves 10, 11, each said valves 10, 11, having air connection lo a corresponding governor bellows or pneumatics 12, 13, 14, 15, the set of said governor' elements 12 to 15 bein bound together by an ann or lever 16 Whic has a rod or connectionQl' to 'the air service limiting valve 18, a governor spring 19 opposing the governor elements 12 to 15 and tending lo close the valve 1S and so raise. the air tension. This v'alve'18` is-a `free out governornfalve serving to releasenll extra suction drawn from thel wind Way 20 through thcjvindway 21 out-of theistriker pneumatic action chests as'22. I The valves 10, normally serve' s nctlon air to the governor elements 12, 15, thus/'causing -the said two 'elements to pull against the governor spring'19'and o en the free` out valve 18 to an extent to regu ate the air supply toa `medium degree oftension,'but whenever the corres onding apertures F or FF, of the tracker lhara'r'e opened by any expression perforation as 6, the valves 10 'release the governorl elements ,12, 1.5, to' the outer air and thus allow a lesspull ,against the spring 19 and a consequentclosingof the valve 18 and a corresponding higher tension of the air service in Windvvays 20, 21 and action chest 22. f

The valves 11 are of normal outer air service to the governor elements 413, 14 the elements 13, 14, thus beingfnormally inac-v tive, but thrown into activity whenever per-- forations as 4, 5 are traveling() posite the respective tractor apertures P, -P, either vof these valves 11 then servingsuction to their respective governor elements' 13 and 14, thus causing an increased pullagainst the vspring 19 and thereby opening the valve 18 to greater extent and correspondingly reducing the air tension inthe 'vvindways 20, and 21, and action chest 22.

That I claim as my invention is 1. A music sheet having a series of closely grouped perforations" in direction longitudlnally of the said sheet, and a continuous slot perforation in the said sheet positioned paralle] to the said group perforations, and

having' itscommencement endto the rear of grouped perforations 're resening the commencement end of the said group perfor-ations, the said continuous and grouped perforations arranged to be sounded together, and an.a dditional perforation in the said sheet positioned transversely opposite said commencement ends and adapted to change the dynamic degree of operation of the .said-first named perfora tions.'

2. A music sheet having a series ofy closely grouped perforations representing a'single note and disposed in direction longitudinally of the said sheet, and a continuous slot note perforation in the said sheet positioned parallel to the said group perforations, and raving its commencement end to the rear of the commencement end ofthe said group perforations, the said continuous and grouped perforations arranged t'o-be soundved together, and an additional perforation in the said sheet positioned transversely op positc said commencement endsand adapted to change the dynamic degree of operation of the said rst named perforations.

3. A music sheet having a series of closely a. sin le note and disposed in 'rection nally ofthe' said sheet, and a continuousslot note. erforation in the said sheet positioned para- .e1 t'o the said group perforations, and having Ylts commencement end `to the rear of *the commencement `end of the saiidl'group4 perforations, the Vsaid` continuous and grouped perforations arranged to be sounded together, and an additional perforation.

in the saidsheet positioned transversely opposite said commencementA ends and adapted to change the degree of air tension of the note actuating devicesada lted to Vbe controlled by the said'note-per orations.

4. A music sheet having note perforations 'in several londgitudinal rows and additional isposed .in longitudinal alineperforations ment at another widthwise positiono.v the rSaid sheet than' the' saidrows of .note perforations, the said additionaly perforatlon's ada ted to vary the dynamic degree of 'stro re of the note striking devices controlled bythe Vsaid note perforationsytvvo of the said note perforations disposed ,with the commencement end of on'e 'of the said perforations in advance 'of-the commencement .end of the other onef'of the;l vsaid two note perforations, thesaid advanced com-.-

menc'ement note perforation l comprising a grou .of perforations and Vbridges adapted to e ect one actuation of a certain note striking device, and the other said note perforation' comprising a single slot of greater length than one of the individual erforations of the said grouped note per oration, thev said continuous and ouped erfora tions arranged to. besoun ed toge er, one

of the said additionaliiynamic perforations .i

positioned adjacent the transverse alinement another note striking device by the slotted of the commencement ends of said two note note perforation. perforations to effect the actuation by the said group note perforation of a lesser de- 5 grec of dynamic action of the correspond- Witnesses:

img note striking device than the degree of PAUL J. HENGGE, dynamic action effected by the actuation of NORMA KEISEB.
